Answer:

Volume of the sphere ( V ) = 1436.02 cm³

Step-by-step explanation:

Explanation:-

Given that the radius of the sphere r = 7 cm

Volume of the sphere

$V = \frac{4}{3} \pi r^{3}$

$V = \frac{4}{3} \pi (7)^{3}$

$V = \frac{4}{3} X3.14 X (7)^{3} = 1436.02$

V = 1436.02 cm³

Volume of the sphere

V = 1436.02 cm³

Tank 1 initially contains 50 gals of water with 10 oz of salt in it, while tank 2 initially contains 20 gals of water with 15 oz

Naddik [55]

$\dfrac{\mathrm dx_1}{\mathrm dt}=\dfrac{2\text{ oz}}{1\text{ gal}}\dfrac{5\text{ gal}}{1\text{ min}}-\dfrac{x_1(t)\text{ oz}}{50\text{ gal}}\dfrac{5\text{ gal}}{1\text{ min}}$
$\dfrac{\mathrm dx_2}{\mathrm dt}=\dfrac{x_1(t)\text{ oz}}{50\text{ gal}}\dfrac{5\text{ gal}}{1\text{ min}}-\dfrac{x_2(t)\text{ oz}}{20\text{ gal}}\dfrac{5\text{ gal}}{1\text{ min}}$

$\implies\begin{cases}\dfrac{\mathrm dx_1}{\mathrm dt}=10-\dfrac1{10}x_1\\\\\dfrac{\mathrm dx_2}{\mathrm dt}=\dfrac1{10}x_1-\dfrac14x_2\\\\x_1(0)=10\\\\x_2(0)=15\end{cases}$

Falling object formula: h=-16t+s

vitfil [10]

Answer:

34.714 seconds

Step-by-step explanation:

According to the question we have:

Formula h = - 16t + s
h = 0
s = 555.427 ft
t = ?

Substitute the given values and solve for t:

0 = - 16t + 555.427
16t = 555.427
t = 555.427/16
t = 34.714
